Both Brillelli and BCMA started out with the same basic SPE engines and each modified them in their own way. Since then Cermark has taken over as sole distributor of SPE in the US as I am informed. Since then both companies have designed their own purpose built engines for aircraft. I would suggest that you take a look at the new engines they are offering now as they are very different and only you can decide what you like.

www.bcmaengines.com and www.brillelli.com

I have no experience whatsoever with Brillelli so I won't comment on them except to say that the people who do seem very happy with their product and exceptional service. I have no reason whatsoever to doubt these people and believe that Brillelli has an excellent product. I have however; bought several BCMA engines and can tell you from experience that they are outstanding and Adams service is exceptional. The simple fact of the matter is that I prefer the design of Adam's engines (particularly the mounting method). I understand that the owners of both companies are very good friends. Here's a picture of Brillelli's 50cc ($495.00) and Adam's new 52cc MT 52Pro, the engine I just bought for $475.00. His new 42cc will sell for $295.00 and is a perfect match for this plane IMO. Make your own mind up.

Thank's for your reply Lou!
About the 42 Pro of BCMA,
i know that is not introduced yet,
but,
will it have an EI built in it?
Also,
how i mount it in my CAP?
Does it come with stand offs?
Should i use an engine mount like these we use on glow-engines?

All of the BCMA engines come with EI, muffler, and stand-offs. The new EI Adam is using is outstanding. When I ordered my engine I gave Adam the distance I needed from the firewall to the thrust washer and he included the stand-offs and mounts to match that distance. Here's is a picture of my 40cc mounted in the CAP.

Lou,

I was just looking at their 100cc. Now taking into account it weighs 100 ounces which is 6.2lbs including the ignition, included mufflers and the backing plate that is right in line with a DA100 which is 5.8 pounds for just the engine and maybe a tad lighter when the DA has the stock mufflers installed and at the price he is offering, I am thinking this would be an excellent engine for my 33% Edge.

I see he is quoting numbers from what looks like ThrustHP for what the thrust gives but I'm at 22.5 pounds now on a 3W 80 which ways one pound less so if you can truly get 50+ pounds of pull on the 27X10 Xoar then I would be easily at 2:1 power ratio

Well it sounds like I just justified buying one [sm=tongue_smile.gif]

Not only that but he's getting those readings testing the engines in Colorado at 5000 feet. He asked me to give him some on the 52cc when I get it as I'm at sea level. He should also be posting some numbers with the new Vess props in the near future. Look at the numbers posted for the MT 52Pro I just ordered for the TOC 30% Extra. I'm sure it was his intent to compete with DA and 3W with his new line of engines and at these prices and specs I think he's doing a great job.

Well,
Bubba and Lou i am a little "confused" to decide.

Bcma over Brillelli?
Brillelli over Bcma?
AHhhh!!!!

I looked at the site of Brillelli and for the 46GT there are three options:

1st is :CH fixed timing ignition

2nd is :CH syncro spark ignition

3rd is :Roy Sholl SS auto advance EI

What's the best?????

I've never used any of those but understand the fixed timing units are real finger biters when starting. BCMA has a electronic advance timing same as the Roy Sholl. I believe Brillelli also quote three different prices depending on what EI you choose. The Roy Sholl EI option is an extra $40.00. That engine also mounts on a standard glo-engine mount which I don't like but you might. Afraid you're just going to have to make your mind up. Nobody here is going to tell you which one to buy. It's just a matter of personal preferences.

Just got back from flying my CAP. WAY too windy! Made the landing nice and easy though having a 15mph head wind on the ground. More like 30 at altitude.[:@][:@][:@] Oh well, there's always tomorrow!!!

Kostas1,

Either engine with the CH or Scholl ignition. Do not get anything with fixed timing. They are a bugger to start and the timing is set only for full throttle.

CH and Scholl ignitions are variable timing and will also adjust the timing for best performance through the whole throttle range.

I talked to Scott from Brillelli yesterday. He is no longer offering the fixed timing option on the 46 cc. One thing I thought that was interesting is the advertised weight. Its 57 oz, thats with the muffler , ignition and the alumium motor mount. Not bad I guess.....Any idea when the BCMA 42 is going to be ready to ship? Althought I think I'm going to go with a Brillelli for my first gas...should yank the Cap around ok......looks like it might come in under 14 lbs to.

That's a great weight! I'm surprised they didn't put that on their engine site. Do the motor mounts come with the engine??

Thats what Scott told me on the phone. He also said hes going to draw up a template for mounting on CAD and start sending them with the engines. No, the mounts are not included, wish they were. Thier another 14 bucks.

Yeah, the site says the ready to fly weight of the engine. That doesn't include the mounts. DA, 3W, and BCMA include the weight of the stand-offs (mounts) in their weights. I believe DA and 3W leave off the muffler weight though. Let me know how that engine works out for you. Sounds like you found what you want.

Will do, I havent ordered it yet. after I do it will be a min. of a 2 weeks wait. Scott says their swamped right now. No problem though, it will be quite some time before I fly. Under a Lake Affect snow warning now, up to a foot of the white stuff.

Well,
my oppinion is that you don't actually need the engine mount/stand-offs weight to compare engines!
I've never seen a glow engine including on it's weight the engine mount@!!
Just my 0.002 cents!

Actually you do need that info. Not for the power but for the weight. When doing small gas engines, say 26cc to 75cc, total engine weight is everything. On glow engines the mounts are often fiberglass which may weigh only an ounce, but even the best gas rail type engine mounts go easily get to 4 ounces since they must be quite strong to handle the torque. Weight for gas engines in the range I mention are most definitely something to consider

Glo engines, both 2 and 4 strokes do not make the kind of torque that a gas engine does. Stick fiberglass mounts on a gas engine and it will not be long until you twist them to the point of cracking them. Besides the vibration differences alone would weaken glow mounts

Well guys. I 'll been debating about either going to gas or glow with this Cap. After careful thoughts and remembering I have a daughter going to college this fall. I decided to go with glow, so I bit the bullet and ordered the GP Cap tonight and ordered the OS 160 from Chief Aircraft since Tower was out of them. Got a good deal with thier email specials. I do, however see a 80-85 inch Yak with a DA in the future, just not right now. After what I've read on here, I'm sure I'll have a blast with the Cap ,no matter want engine I would of went with. I've always been a Cap fan, love to see them fly at full scale airshows so I knew this was the plane for me when I first saw it. I am very thankful to all you guys that answered all my questions and PM's. I'll keep you all updated , cause I'm sure I'll have some more questions as time goes on. Sewerdude

Sewerdude...

You'll really like this plane. It's very fun to fly, easy to fly, and will do about anything. I really like mine. Nice and light and very powerful. Even at my elevation.

thanks
Barry

Post your "progress-pics" as soon as possible!

No No No, you must have forgot to tell her that you are investing in her future by learning to fly bigger planes, that way you can get sponsored and send her to a better college, she'll have to wait just a bit longer. [sm=wink_smile.gif] I'm just kidding.

Like Barry said and I could not agree more, your gonna love this plane. It's a sweetheart. I'll also go along with posting progress pics as soon as possible. I'm just as guilty but we have not seen any type of a build thread on this plane yet. You could easily just do it right in here, hint hint [sm=wink_smile.gif]

A very good idea Bubbagates!

I did do a Full User Review on this thing but it goes together so easy that there's not much to say about it. Definately need some new main wheels and a different tail wheel assembly. I don't think there was anything else I could find wrong with the darn thing. Really sweet build and a great flyer. You'll love it with that 160 in it. I ran the Bisson Muffler with a APC 18x6W prop on PowerMaster 20/20 and the thing pulls 18 pounds of static thrust so there's plenty of power. Wish I had knew you were going for the 160. I was thinking about selling mine now that I have the 40cc in the CAP. At least be sure and post lots of pics and enjoy!!!

Lou55,

I don't know why you say this. I find the wheels are very light and at the same time sturdy enough to sustain any kind of (bad) landings. And the tail wheel is strong enough and has plenty of authority on the ground.

The same wheels and tail assembly that on the GP Performance Series Yak, and I have not experienced any problems with them, so far. Esthetically they are not perfectly true to scale, but they do their intended purpose, and they are very lightweight. I am asking, not for the sake of arguing, maybe you see something I have missed and I want to know before it’s too late.

I have had my tailwheel assy pull out of the fuse and break off the plastic guide in the rudder. The main wheels are foam and wear badly. I also have a busted rim on one from a slightly hard landing that should not have broken it. IMO Great Planes makes some really good wheels but these aren't them.

I used to say that the tailwheel was fine but after around 100 flights on a grass runway that is somewhat rough, the tailwheel finally let go. The same thing happened on my Performance series Ultimate at about the same number of flights.

I replaced both with the sullivan unit and have been fine since

Both planes are still using the stock main wheels. Yes, they will get a flat spot if left sitting on them too long but it comes out pretty quickly
